COIN-CONTROLLED LOCKING MECHANISM.

Specification of Letters Patent.

Patented Dec. S, 1914.

Original application filed June 12, .1911, Serial No. 632.716. Dividedand this application filed August 21,

To all 107107) it may concern Be it known that I, FRANK J. Rowsn, acitizen of the United States, residing at Pawtucket, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements inOoin-Controlled Locking Mechanisms, of which thefollowing is a specification.

My invention relates to a locking device controlled by a mechanism inwhich a coin inserted in the casing constitutes one of the operativeelements, and the present application is a division of patentapplication, Serial No. (332,716, filed. in the United States PatentOllice June 12, 1911.

The essential objects of my invention are to prevent the possibility ofthe insertion of a coin in the slot in the front of the casing after thedoor to which the casing is attached is closed; to make it possible tore ciprocate the locking bolt at will after a coin has been inserted anddischarged, and before the door is closed so that the turning of theknob at such a time will not involve the necessity of inserting a secondcoin; to render the bolt operation and control available only to theperson behind the door after the door is closed; to guard againstaccidental ma nipulaticn of the parts by the person behind the doorwhereby the coin slots will register in the front of the casing; toprovide means for locking the casing to the door which shall beinaccessible to a person without a key to the door of the casing; and tomake the mounting or detaching of the operating handles subject to likeconditions of accessibility.

Further objects are to provide a facile means for disengaging the coinfrom the coin guide; to provide a certain means for guarding thedischarged operative coin, and insure the (flischarge and separation ofan inoperative coin without operation of the mechanism. 1

Other objects and advantages will be hereinafter referred to inconnection with the description of the mechanism.

To the above ends essentially my ll1YOIl-.

tion consists in such novel parts and arrangement and combination ofparts as fall within the scope of the appended claims.

In the accompanying drawings which Serial No. 716,195.

form a part of this specification, Figures 1, 2 and 3, are front, rear,and plan elc *ations respectively of my device shown mounted in a door,showing adjacent parts of the latter broken away, Fig. -il, a frontelevation of the same with the front wall removed, Fig. 5, a section online 5, 5, of Fig. 4-, Fig. (3, a see tion on line 6, 6, of Fig. 15,Fig. 7, a section on line 7, 7, of Fig. 9, Fig. 8, a section on line b,8, of Fig. .2, Fig. 9, a section on line 9, S), of Fig. 5, Figs. 10, and11, detail views out the bolt o icrating pawl, Fig. 12, a plan of theYale locking mechanism showing the adj accnt parts in section, Figs. 13and leh'views taken on lines 13, 13, and 14, 1-4, rcspectivelv of Fig.5, Fig. 15 is a view taken on line 15. '15, of Fig. 5, Fig. is, atransverse section of the coincontrolled mechanism taken on line 1o, 16,of Fig. Y15, and Fig. 17, a detail view oi" the pressure plate.

Like characters of reference indicate like parts throughout the views.

The casing inclosing my device may be of any form best adapted tocarrying the operative parts. In the form thereof herein shown .itcomprises a front wall 16, top and bottom walls, 18 and 1t), and sidewalls 20 and The front wall 16 is provided with a coin slot in anintermediate portion below a visual orifice or window 23 at one side,and a Yale or other well known lock upon the other side. In the lowerportion of this wall is an opening25 closed by a removable door 26 alsoprovided with a lock 27.

Fixed to the taco of the door 30, which is typical of any door leadingto a small room or cabinet, is a plate 31 which constitutes the backwall of the casing, andwhich is fastened to the door by screws 32. The

plate 31 has its upper portion cut away as i at 34 to receive therein avertically slidable plate 35 having an offset upper portion 37 restingagainst guide pins 38. Upon the lower portion of the plate 35 is a stud39, and upon the plate 31, stop pins 40 and 4:1.

The front wall 16 of the casing, together with its integral side walls,are removable from the back plate 31, and may be detached by one havingaccess through the door 26 by virtue of the following ci'innections. Inthe bottom wall is fixed a plate 43 whose upturned flange 4% isperforated to receive to the top wall 18 by screws 50, and pro videelwith a downturned lip 51 which engages the back face of the ofisetportion 37 v of the slide 35.

Resting against the plate 31, as shown in- Fig. 13, is a horizontallydisposed bolt comprising a flat shank 53, and a head 54; the formerhaving its rear end provided with a longitudinal guide slot 55, anoutturned finger or projection 56, and a downward finger 57. The forwardportion of the body 53 is also downwardly extended as at 58. The bolt isguided by a pin 59 in the plate 31 extending through the slot 55, andthe bolt head is movable into and out of a bolt receiver 60 fixed byscrews 61 or otherwise to the door jamb 62. The face of the bolt isprovided with a horizontal track 61 terminating in a vertical contactedge 65. Passing through openings 66 and 67, in the door 30 and plate 31respectively is a hollow shaft 68 provided with a handle or lever 69 onits outer end, and upon whose inner end is fixed a disk 70 provided uponits upper edge with an elevated curved cam shoulder 71. contacting withthe stud 39, and having two downwardly inclined projections 72 and 73.On the upper margin of this disk is a stud 75 upon which rests a pawl 76pivoted at one end upon a pin 77 in the plate 31. The pawl has aconcavity 78 in its upper edge andv another 7 9 in its lower edge. Thestud 10 is a stop to the travel of the disk in one direction, and aspring 81, provided with an intermediate coil 82, and fixed by solder orotherwise to a partition plate 83 in the easing presses with its freeend against the arm 7 2 of the disk forcing the arm 73 against the stopscrew 11, which is for operative purposes the limit of the travel ofsaid disk in the direction of the arrow. Under certain conditions thescrew 411 is removed, in which case the pin 40 is the stopping agent.Under operating conditions the cam edge 71, through the pin 39, keepsthe slide 35 elevated, thus locking the housing against the back plate.When, however, it is desired to remove the housing the door 26 is removed, and the operator, through the opening 25 unscrewsand removes themember 41 whereupon the disk swings against the pin 40, and the pin 39drops from its elevation permitting the slide 35 to fall and disengagethe lip 51. The bottom portion of the casing is readily detached becausethe screws 16 are directly accessible through the opening 25.

It is sometimes desirable to operate the bolt 53 independently of thecoin operated mechanism. To this end a key operated lock is employed. Inthis instance a Yale lock mounted in an opening 85 in the front wall,

comprising the usual parts including the front plate 86, key way 87,cylinder 88 and cam 89, best shown in Figs. 6 and 12. The cylinder 88 isprovided with perforated lugs 91 and adjacent the latter is a horizontalpost 93 integral with the front plate. Resting against the end of thepost and a shoulder 91 upon the wall 20 is a plate 95 separated byspacing blocks 96 from a second plate 97. The plates 95 and 97 areperforated to admit binding screws 100 and 101, whose threaded endsengage respectively the perforated lugs 91 and the shoulder 9 1 and post93. Rotatably mounted in an opening 102 in the plate 95 is a hub 103provided with a diametrical slot 101 in one end to receive the cam 89,and provided at its other end with an arm 105 contacting with the innerface of the lug 56 on bolt 53, against whose outer face presses a flatspring 106 fixed by screws 107-to the wall 20 of the casing. It will beseen that the described lock through the arm 105 coperates with thespring to reciprocate the bolt.

For the purpose of registering the number of coins employed in operatingthe machine a common registering device 109 is fixed, adjacent thelocking device, to a plate 110 extending from the casing wall and behindthe opening 23. Its operating shaft 112 has upon its end an arm 113 fromwhose free end pivotally depends a hook or link 115 connected with anintermediate portion of a counter operating lever 117 pivoted near oneend upon a stud 118 inthe plate 97, and having at its other end adownwardly inclined cam edge 120. Upon the pivoted end of this lever isan offset downwardly inclined finger 122. This lever is verticallyvibrated by mechanism hereinafter described, so that at each vibrationthe operating shaft 112 of the register is oscillated.

Referring more particularly now to the bolt actuating mechanism which isof the coin controlled type wherein the coin be comes an element. ofoperation, is the main shaft mounted in a plate 126 constituting a partof the front wall 16 of the casing and extending loosely into the hollowshaft 68. Upon its outer end is a handle or knob 127. Mounted upon theshaft 125 and oscillatory therewith is a coin carrier, comprisingparallel side plates or disks 129 and 130 fixed to the shaft and rigidlyconnected by upper and lower bars 132 and 133. The disk 129 is providedwith a coin slot 135 adapted when in normal position to register withthe slot 22 in the front wall of the casing, and has a marginal shoulder136 upon its upper portion adapted to contact with a stop 137 in thefront wall o the casing.

Loosely mounted on the shaft 125 is a cam plate 138 in slidable contactwith the disk 130. Pivoted upon a pin 139 upon the upper margin of thecam plate is a lug 1410 integral with the upper end of a downwardlyinclined guide plate lkll located below the coin slots, provided with adished and pointed lower end portion 1 12 and resting against aneccentrically disposed pin 1513 upon the disk 129. The plate 1 11 servesas a coin guide, holder, and presser, the coin 141 1 dropping from thecoin slots travels down its inclined face. The plate 111 is normallypressed against the pin 143 by a ll-at spring 1&5 fixed to its upper endand pressing against shaft 125. Cooperating with this plate is apressure plate 14 0 fixed by screws 147 or otherwise to the disk 130,and a bearing edge 1 18 parallel with the plate 111 and normallyinter-spaced therefrom a distance equal to the thickness of a coin. Theplate, shown in Fig. 17, comprises two parts including an inner plate150 provided with a bent projection or lip 151 underlying the coin belowthe horizontal diametrical line thereof.

Cooperating with the pressure plate 14:6 is a coin holding lever 153, asshown in Fig. 1G, loosely pivoted upon a stud 15 1 in the plate 129 andheld thereon in this in stance by a cotter pin 155. Near its outer endupon its inner face the lever is provided with a transversely disposedbeveled groove 156 to form a coin rest. A flat spring 157 underlying thelever 153 presses the same toward the coin. A stop pin 158 in the bar133 determines the extent of outward movement ofthe arm 153. A key pieceor lever 159is pivotally mounted on a stud 160 extending from the disk129 and is adapted to oscillate to a position intermediate the lever 153and the disk129. A stud 162 on the front wall 16 projects into the pathof the lower extremity of the lever 159 so that contact therewith nearthe close of an oscillation of the *arrier disks serves to disengage thelever 159 from the coin holding lever 153. y The oscillatory coincarrier is held in up right normal position with the coin slotsregistering by means of a spring device consistingof apin 165 on thedisk 129 from which depends a link 166 engagingthe free end 168 of acoiled spring 109 fixed on a bar 170 fastened at one end in the frontwall of the casing, and at the other end in a lug 171 held by screws 172to the wall 21 of the casing.

The cam plate 138 is normally downwardly pressed through a pin 174supporting a link 175 which engages the free end of a spring 177 whosecoil 178 is fixed on the bar 170.

The coin carrier, which is adapted to operate with a particular kind ofcoin only, is shown in normal inoperative position in Fig.

9. The coin is inserted through the slots 22 a and 135 and slides downthe plate 1&1 until it is stopped by the pressure plate 146, 150, theprojection 151 andthe beveled seat of the coin holding lever 153, asshown in Figs. 9,16 and 17. The handle 127 is now turned part of arevolution till "the parts approach the position shown in Fig.15; Thismovenient, combined with the downward pull of spring 178 and therelative pressure of the stud 112-5 upon the plate 1-111, forces thecoin l-l l into firm contact with the pressure plate 140, locking theparts together. The delivcry of the coin, which is continuous with thedescribed operation, is effected by the transverse movement of the coinholding lever 153, shown in Fig. 10, which is disengaged or released bythe removal of the key lever 159 when the latter came in contact withthe stud 102 during the oscillatory move- 1 m'ent, so that the coinassumes the position indicated in broken lines in Fig. 16. Thesinmltaneomi pressure of the end 142 of the coin plate contributes tothe forcible expulsion of the coin which drops to the bottom of thecasing. The carrier is now returned to normal position by its spring,and the auxiliary parts assume the positions shown in 141.

A coin guard comprises an inclosed plate 182 with rearwardly bentlateral car 183 near its upper end journaled on the stud 190, and with avertical rearwardly directed prolection 1S5 adapted to operate as an 192and is provided at its other side margin with an car 193. The plate 192and ear 193 are perforated to loosely receive a pintle 196 fixed in lug197 on the vertical extension 1.99 or the partition 83. The plate 192 isnormally pressed downwardly by a spring 200 fixed to the pintle andbearing against said a As shown in plate and the extension 199. Fig. 4-.the plate 192 is provided with a horinontal lug 203 located in the pathof a finger 20-t onan intermediate portion of the key lever i159. wardtravel of the finger 20 1 at the end of the oscillation of the carrierelevates the plate 191 into overlapped position. I1", however, arim-operative coin passes down the plate 141 itdrops from said platedown upon the inclined surface of the plate 191 wherei by the coinisdeflected to fall down between the partition 83 and the wall of thecasing and pass through a coin slot 206 inthe bottom wall of the casing.A stud 207 on plate 16 contacts with finger 20 1 to swinglever 159dining the return oscillation of the parts. i i

As shown in I ig. 15 the downi I It is desirable that the coin slotsshould not register with each other to admit a coin after the door hasbeen closed until the operator makes the condition possible. Certain ofthe structure employed in this con nection is the following: The disk130 is provided with a shoulder 208 upon its edge as shown in Fig. 15.Upon the lower margin of the cam plate 138 is a marginal inner shoulder209, adapted to coincide with the shoulder 208, and an outer shoulder210, connected with the inner shoulder by an inclined edge 211. Theshoulder 210 is outside the path of the shoulder 208. he shoulders 208,209 and 210 cooperate with an upright lever or pawl 215 provided with abroad fiat top or end face upon which the shoulder 210 normally restsunder pressure of spring 177 as shown in Fig. 9. The pawl 215 is looselymounted at its lower end upon the bar 170' and is inwardly pressed by acoil spring 217 fixed to the bar and having its free end 218 restingagainst the back of the pawl. The lower portion of the pawl is laterallyextended as at 219 and on the extended portion is a stud 220 projectinginto the path of the arm 73 of the disk 70. When the coin carrier hasreached the limit of its oscillation as shown in Fig. 15, the pawl hasalready been thrown inwardly by the spring 217 into the path of both theshoulders 208 and 209 so that when the handle 127 is released saidshoulders return under spring pressure to rest on the top end of thepawl 215, so that the coin slots do not register, and the shouldercannot be released to return the carrier to normal position until thearm 73 is swung against the stud 220 thereby forcing the pawl 215 backinto the position shown in Fig. 9. The original retraction of the bolt53 is effected by the return oscillation of the coin carrier through thefollowing agency. A pawl 222 shown in detail in Figs. 10 and 11 isprovided with a perforation 223 near its forward end to receive a pivotpin 2242 in the elevated portion of the rear face of the disk 130,whereby the pawl is slidably mounted adjacent the bolt 53. This pawl hasan intermediate cam edge 226, and an inturned lug 227 upon its outerend. Its pivoted end is provided with a marginal cavity 228. Below thepivotal point is a stud 229, and near its forward end, a stud 230. Alooped spring 232 has one end engaged in the cavity 228 of the pawl andthe other end fixed to the disk 130 whereby the rear end of the pawl,the end provided with the lug, is downwardly pressed, keeping the lug227 down upon the cam edge 233 of the cam plate 138. In Figs. 13, 14,and 15 the operation of this pawl is best disclosed. The studs 229 and230 are normally below the track 64, of the bolt, the lug 227 resting onthe cam edge 233 of cam plate 138, and the stud 229, as shown in Fig.

shown in Fig. 15 to its extreme forward position, the lug 227 beingelevated by the rising. of the cam edge 233 to the position shown in thelast mentioned figure. The described movement carries the stud 230 upupon track 64L and along the same against the edge 65 forcing the bolt53, against the the opposite pressure of spring 106, to the left toposition 230 in Fig. 14, thus disengaging the bolt head 54 from itsreceiver 60, the position of the stud 229 being at 229 This position ofthe track is shown in broken lines in Fig. 14. This movement haspermitted the pawl 215 to be pressed inwardly by its spring 217 into thepath of the shoulders 208 and 209, so that when the handle 127 has beenreleased by the operator the carrier returns a slight distance only andis checked by the pawl 215 in contact with said shoulders. This slightreturn of the carrier also carries the stud 230 to the right whichpermits the bolt and its track under the pressure of spring 106 to passto the right into its receiver, the final position of the stud 230 beingabove and near the free end of the track as at 230 Thus even after thedischargeof the coin from the carrier the'bolt 53 may be reciprocated atwill any number of times without inserting a new coin until the door isonce closed. During the described reciprocations the stud 229 has movedinto a position such as 229 in Fig. 14, so that its contact at thatpoint with the top edge of the pawl 76 will depress the latter to suchan extent that the stud 75 cannot move to the left along its curvedlower edge further than the point 75?, in Fig. 14:. This conditioninsures against the leg 73 of the plate by accident contacting with thestud 220 during this reciprocatory condition, of the bolt 53 whereby thepawl 215 would be tripped. When however the door closed the bolt isthereby thrown toward the left moving the track 6d from beneath the pin230 at 230 and permitting the latter to be forced by its spring 232 backto its original position and slightly moving the stud 229 to the left sothat the pawl 76 may rise to its highest dotted position in Fig. 14, andthe stud 7 5 move easily t the left if necessary, to the position 7 5.

The described conditions make it impossible for a person in front of thedoor to insert a coin, and his manipulation of the handle 127 operatesnothing. The person behind the door can whenever he desires throw backthe bolt by turning the handle 69 which throws the shoulder 71 of thedisk 70 against the finger 57 on the bolt.

By reference to Fig. 15 it will be seen that when the coin carrier isnear the end of its advance the cam edge 226 of the pawl 222 strikes thefinger 122 of the counter operating lever 117 and depresses the free endof the latter and operates the register 109 through the hook 115 and arm113.

In Figs. 2, 3 and 8 is shown a preferred connection of shaft and handlefor use upon the back face of the door. The handle (39 comprises indetail sleeve 235 provided near its outer end with an internal squaredshoulder 236. Thesleeve has integral with its outer end and at a rightangle thereto a handle or arm portion The tubular shaft 68 has a solidportion 239 terminating in a squared shoulder 236. The portions 239 and2&0 are longitudinally bored as at 241 to admit a screw 212 whose head243 abuts against the portion 239, and whose opposite or threaded end244: engages the threaded central perforation 241-5 of a locking disk246 abutting against the shoulder 236 flush with the end of the sleeve.served that the handle 69 is detached only by access through theinterior of the casing by means of a screw driver operating on the head243., A. collar 248 may be fixed by screws 249 to the rear face of the(1001' around the shaft 68 if desired.
